MUSIC-LEAF TURNER.a

To all whom it may concern.-

' Be it known that I, WILLIAM G. BENSON, a citizen of the United States,residing at Mooresville, in the county of Livingston and State ofMissouri, have invented certain new and useful Improvements inMusic-Leaf Turners; and I do hereby declare the following to of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to new and useful improvements in music-leafturners, and more particularly to that class adapted to be used inconnection with racks or directly upon a piano or organ.

The object of my invention is to produce a cheap, which will be positivein its operation.

A further object is to provide a device which can be operated by hand orby the foot of the player.

A still further object is to provide means for accommodating said turnerto different lengths of leaves.

Further objects and advantages will be hereinafter referred to in thespecification and pointed out in the claims.

In the accompanying drawings, which are made a part of this application,I have shown the preferred form of my invention.

In said drawings, Figure 1 is a plan view of my device adapted to beused in connection with a piano, organ, or the like. Fig. 2 is alongitudinal sectional view through the device as seen from the dottedline 2 2, Fig. 1. Fig. 3 is a detail sectional view, on an enlargedscale, as seen from the dotted line 3 3, Fig. 1. Fig. 4 is a detailsectional view,

on an enlarged scale, as seen from the dotted line 4 4, Fig. 1. Fig. 5is a detail perspective view of one of the leaf-engaging arms removedfrom the turner. Fig. 6 is a detail sectional view, on an enlargedscale, as seen from the dotted line 6 6, Fig. 1. Fig. 7 is a plan viewshowing my improved music-leaf turner used in connection with thewellknown form of music-stand, and Fig. 8 is a similar view showing theopposite side of the music-leaf turner proper.

Referring to the figures by numerals of reference, 1 indicates the bodyor frame of my improved leaf-turner, to the lower edge of which aresecured curved arms 2, by means of which said body is secured to. apiano or like musical instrument. To the Specification of LettersPatent.

Application filed March 30,

l front of said body portion 1 is secured a vertically-disposed rod 3,said rod being rotatably mounted in suitable bearings 1. To the lowerend of the rod 3 is secured a con- 1 trolling-lever 5, and near theupper end thereof is secured a laterally and upwardly extending arm 6,said arm and lever being rigidly secured to the rod. Pivotally securedto the upper end of the rod 3 are a series of leaf-engaging arms 7, saidarms being so disposed upon said rod that they will travel in a uniformplane. Secured to the l upper side of each of said arms are auxiliaryarms 8, said arms being vertically disposed and having lateralextensions at their upper l ends, which extensions are pivotally securedto the rod 3. The objects of the lateral extensions at the l upper endof the auxiliary arms are twofold in that they brace the auxiliary armsand I compensate for any undue strain thereon and l also serve to retainthe arms 7 in thelr hori- I l zontal position and prevent the same fromsagging, which is an important function, from the fact that were theleaf-engaging l arms not supported they would in time sag to such anextent that they would extend below I the engaging and releasingmechanism at one F side of the frame.

Pivotally secured to the vertically-disl posed section of the members 8are controll ling members 9, said members having one of their ends 10curved, as best shown in Fig. 2,

f so that when the leaf-engaging arms '7 are disposed at one side ofsaid rod 3 a leverage l will be exerted upon the curved ends of the lcontrolling members 9 for a purpose to be i hereinafter set forth.Disposed in a housing at one end of the frame 1 are springs 11, saidsprings being equal in number to the number I of leaf-controlling arms.

' One end of the springs 11 are secured to a l shaft 12, and to theopposite ends thereof are secured rods 13, said rods being connected tothe curved ends 10 of the controlling-arms 9 by means of links 14. Theopposite ends of the shaft 12 are disposed in ways 15, whereby i saidshaft may be moved longitudinally v hen desired. Secured around theshaft 12 and disposed laterally through an adjacent part of the frame 1are adjusting-rods 16, said rods having their outer ends threaded andprovided with adjusting-nuts 17, by which 1 construction the tensionupon the springs 11 may be increased or diminished. The leaflengagingarms 7 are each provided with spring-controlled engaging members 18,said 1 1 is a leaf-supportingbracket 10, said bracket members being soarranged that when the 1 arms 19, carried thereby, are forced togetherthe engaging members 18 will be separated, so that a leaf of the musicor book may be inserted therebetween, and when said arms 19 are releasedthe springs 20 will bring said en- 1 gaging members 18 together andclamp the leaf thercbetween. Secured to the frame 1. in juxtaposition tothe springs 11 and in the path of the arms 7 is a device adapted toreceive and intermittently release said arms 7, said device comprising apair of horizontallydisposed movable parallel arms 21 and 22, to

being adjust-ably secured to guide members -11 on the opposite ends ofthe frame 1, said bracket being held in its adjusted. position by meansof thumb-nuts 41- as best shown In operation the sheets of music or abook l is seated upon the bracket 10 and the meml l l the rear ends ofwhich is rigidly secured a controlling-bar 23.

The arms 21 and 22 are disposed parallel with a pair of arms 24 and 25,said arms being secured to the frame 1 in any preferred way. The arms 21and are movably secured to the arms 24; and 25 by means of pins 26 and27, the pin 26 being carried by the arm 2 1; and extending through anelongated slot 28 in the arm 21, while the pin 27 is carried by the arm.22 and extends through an elongated slot 25) in the arm 25. Pivotallysecured to the free end of the arm 21 is a latch or dog 30, said latchbeing so arranged that when the arms 7 are being moved inwardly betweensaid arms 21 and 22 said latch will move upwardly and allow said arms 7to pass thereunder, and after said arms 7 are seated between the arms 21and 22 the latch 30 drops down in front of said arms and retains themtherebetween, and to 1 more readily dispose the latch in front of thearms after said arms have been inserted between the arms 21 and 22 Idispose a spring 30 between the tapered end of the arm 21 and the latch.30, so that said latch will be normally held in its lowered position,this construction being shown. in Fig. 3 of the drawings. The arm 22 isof less width than the arm 25 and is provided upon its upper edge with alinger 31, said linger being designed for a purpose to be hereinafterset forth.

Secured to the depending end of the controlling-bar 23 is avertisally-disposed red 32, said rod connecting at its lower end with ahoriZontally-disposml. lever 33, which is pivoted at its center to therear of the future l 1. The lever 5.3 is pivoted at its opposite link issecured. to the rod 34: by means of a securing-bolt 38, said boltpassing through the end of said link and into a socket formed. in theenlarged. end 39 of the rod 341. i isposed laterally across the face ofthe frame hers 18 secured to the leaves that are to be turned and thearms 7 disposed between the arms 21. and 22. After the leaves have beeninserted between the members .18 all the arms 7 can be disposed at onetime between the arms 21 and 2 through the medium of thecontrolling-lever 5, rod 3%, and arm. (5, the upwardly-extending portionof the arm 6 being dispesed i'it the path of the arms 7, so that whenthe coiitrolling-lever 5 is (liSbiiStWl to the opposite side of the rod.3 from that shown in Fig. 1 said rod and arm (5 will rotate and. thearms 7 disposed between the arms 21 and 22. After the arms 7 are thusdisposed and one page of the music played the eperatcr presses thecrank-arm 53(3 dowm wardly, which operation elevates the controlling-bar23 through the medium of the rods 32 and 34- and lever 03 and raises thearms 21 and 22 until the latch 30 passes out of the path of the firstarm 7, releasing said arm, so that the spring 11 through the medium ifthe controlling member t) and link land arm 13 will rotate said arm '7on the shaft 3 until the leaf is disposed on the opposite side of theframe 1. At the same time that the latch 30 is disposed out of the pathof the first arm 7 the linger 31 is disposed between. the first andsecond arm 7 and the remaimler of the arms retained between the arms 21.and 22 until the latch 30 is again lowered into position, when thefinger 31. will pass out of the path of the remaining arms 7 and allowthe next succeeding arm to engage the latch 30, said operation beingrepeated until all of the arms 7 are released. After all of the arms 7have been released from between the arms 21 and 22 new sheets can bedisposed between the seeuring members 8 and all of the arms again.disposed between the arms 21. and 22 by rotating the shaft 23 throughthe medium of the controlling member 5.

As best shown in Figs. 1 and a of the drawings, it will be seen that thelateral extension upon the crank-arm 36 is provided with a se; ies ofopenings, so that the link 35 may be adjusted thereon as desired. Itwill also be that said crank arm 36 is provided with acontrolling-spring 36, whereby said crankarm and parts secured theretowill be returned to their normal position after an arm 7 has beenreleased.

In Figs. 7 and 8 l. have shown my device as applied to the usual form ofmusic-stand, and when so applied the link 35 and crank-arm 36 aredispensed with, and a controlling member 13, carried by a stand 4 1, issecured to the rod 34, as best shown in Fig. 7 of the drawings. Thecontrolling member 43 eX- tends downwardly to near the bottom of therack 44 and is provided with a laterally-disposed section 45. In thisconnection when it is desired to release one of the arms 7 the musicianplaces his foot on the section 45 and presses downwardly thereon, theaction upon the parts of the turner being the same as when pressure isbrought to bear on the crank-arm 36. After the arm 7 has been releasedthe member 43 is returned to its elevated position through the medium ofa spring 46, said spring being disposed around the member 43 and betweena head 47, secured to said member and one of the securing-brackets 48,carried by the stand 44. The frame I is secured to the stand 44 by meansof a cross-head 49, secured to the rear oi said frame, and a clip 50 atthe lower edge of said frame. As best shown in Fig. 8, the rods 30 and34 and the lever 33 are disposed in a way 51., cut in the back of theframe 1, so that said frame can be disposed upon the front of a pianowithout said parts contacting the face thereof.

What I claim is 1. Inra leaf-turner, the combination with a frame,- of alocking device comprising a pair of arms rigidly secured to said frame,a pair of vertically-movable arms securedto said rigid arms and paralleltherewith, a swinging latch pivotally secured to the upper movable arm,a spring disposed between the end of said arm and latch whereby saidlatch is nor mally held in its lowered position a finger rigid with thelower movable arm and pro jecting upwardly therefrom, a controllingbarrigidly secured to said movable arms, and means to operate saidcontrolling-bar whereby the movable arms will be raised bodily and thedevices interposed between said arms released one at a time.

2. In a leaf-turner of the class described, the combination with a framehaving a shaft rotatably mounted thereon, lea'l engaging devices pivotedto said. shaft and disposed in a common path, controlling memberssecured to said leaf-engaging devices, said controlling members havingone of their ends curved and rotating around said shaft with the innerface of the curve engaging the shaft, and means secured at one end ofthe frame and at the opposite end to the controlling members to swingsaid leaf-engaging members on the shaft.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
